Orthodox Monastery of the Transfiguration is a monastic community for women in the Romanian Episcopate of the Orthodox Church in America. It is located in Ellwood City, Pennsylvania.

The community was founded in 1967 under the omophorion of His Eminence Archbishop Valerian, Archbishop of Detroit and the Romanian Episcopate with Mother Alexandra, formerly Princess Ileana of Romania, as the first abbess. Mother Alexandra put into formation her dream of a monastic community in English for Americans. In 1987, then-Abbess Benedicta left the Transfiguration Monastery to begin the Dormition of the Mother of God Orthodox Monastery with two other nuns from this monastery.
The community consists of women living the monastic tradition of a Christ-centered prayer life for the monastic members.
